Query regarding performance-differences, in using a "servlet" VS "PHP module"

Hi all.

I was just doing some rudimentary research on what would be the best
solution to implement server-side operations of our webapp.
The "servlet" and "PHP" seem two widely used solutions.

However, there is one important thing that struck me.

Looking at http://www.tutorialspoint.com/servlets/servlets-life-cycle.htm,
it states that every new client-request to a servlet, spawns a new thread.
On the other hand, looking at
http://php.net/manual/en/internals2.structure.lifecycle.php, it states that
the Apache module MIGHT map different requests to a single process (with
the CGI model DEFINITELY using the one-process-per-request implementation).

Looking at the above, it seems that using Apache Tomcat to host a servlet,
is better than running a PHP module in Apache (as far as
resource-requirements are concerned at the server).

Is my understanding correct?

I will be grateful to any clearances on my doubts :)

Regards,
Ajay

It's not a point of differentation. You can run either technology many
different overlapping ways.

Thanks Eric for the reply.

So, is it possible to run PHP in Apache, with each client-request being
serviced in a different thread (and not a new-process-per-new-request)?
Because, it is a well known fact that a process is a much-higher entity
than a thread.

If not, Apache-Tomcat looks to be clear winner over PHP-in-Apache (please
correct me if I am wrong) :)

Please, I must say at the outset that I am not in favour, or against any
technology, but just wish to gauge some inputs on Apache internals, from
the Apache experts :)

Sorry, I meant a "much-heavier (resource-consumption wise)"

Running mod_php in a threaded webserver is out of favor, but it's
possible. You can also run a single-threaded webserver with PHP
embedded in it, or a pool of php processes waiting for fastcgi
connecitons. See php-fpm.
